test: do not set concurrency on parallelized runs
Our CI already run test files in parallel, having `node:test` spawns
child processes concurrently could lead to oversubscribing the CI
machine. This commit sets the `concurrency` depending
on the presence of `TEST_PARALLEL` in the env, so running the test
file individually still spawns child processes concurrently, and
running the whole test suite does not oversubscribe the machine.
